  text: "In recent years, a variety of different approaches\r\nhave been proposed
    to tackle the problem of scaling and placing\r\nnetwork services, consisting of
    interconnected virtual network\r\nfunctions (VNFs). This paper presents a placement
    abstraction\r\nlayer (PAL) that provides a clear and simple northbound interface\r\nfor
    using such algorithms while hiding their internal\r\nfunctionality and implementation.
    Through its southbound interface,\r\nPAL can connect to different back ends that
    evaluate\r\nthe calculated placements, e.g., using simulations, emulations, or\r\ntestbed
    approaches. As an example for such evaluation back ends,\r\nwe introduce a novel
    placement emulation framework (PEF)\r\nthat allows executing calculated placements
    using real, containerbased\r\nVNFs on real-world network topologies. In a case
    study,\r\nwe show how PAL and PEF facilitate reusing and evaluating\r\nplacement
    algorithms as well as validating their underlying\r\nmodels and performance claims."
